Weeke CNC Machining Center, Model BHC 350 S/2

1 Technical Specifications MS #29015-29018, February 14, 2006 Page 1 Weeke CNC Machining center , Model BHC 350 S/2 Weeke 's BHC 350 S/2 is a truly industrial machine designed primarily for routing, boring, and grooving of flat components without special workpiece fixtures. Weeke is uncompromising with high quality standards. They are an ISO 9001 certified machine tool builder. Weeke uses world class suppliers for critical items not made in house. In fact, most of the externally sourced components are sold and serviced on a worldwide basis and, of course, here in the Insistence on quality and highly industrialized components results in a very stable process--one that requires a minimum of inspection, preventive maintenance, or repair. The BHC 350 S/2 is constructed on a steel frame, with heavy steel ribs (gusset plates) welded to the frame inside the base to insure stability. The design and substantial mass provide a solid, vibration-free platform for the Machining head.

2 The head rides on THK linear motion guides. In fact, the X-, Y-, and Z-axes are all supported on THK machine tool guides. THK guides were designed to produce straight line tracking at high travel rates, and they have outstanding stability--both in the radial and side directions. The X-axis is driven by a zero-backlash, pre-loaded helically ground rack and pinion gear system. The Y- and Z-axes are driven by high precision ball screw. Indramat solid state drives and digital AC servo motors are utilized to move the axes. Fiber-optic cables are used for communication between the drive system and the machine control. Technical Specifications MS #29015-29018, February 14, 2006 Page 2 The BHC 350 S/2 features a Windows based control with intuitive programming software. In addition to the software in the machine control, a program is included (on CD-ROM) for installation on other PC s. With a PC in the office, the machine can be programmed off-line using the same intuitive icon driven software the operator has in the machine's computer control.

3 Vertical Routing Weeke Unit #1042 A liquid cooled kW vertical router motor is located at the front of the spindle carriage. The spindle motor utilizes grease sealed ceramic bearings for higher performance and maximum bearing life. This spindle also uses the HSK63 standard for the taper in the spindle and the accompanying tool holders. The HSK63 design is the latest technology in tool holding systems and has been proven to be stiffer (less deflection) and much more accurate than conventional tapered shank designs, especially at high rpms. Additionally, the exceptional mass and rigidity of the machine's frame helps the router achieve a good surface finish with high feed rates and long tool life. Frequency Inverter A solid state frequency inverter manufactured by KEB is utilized to power the router. The inverter output is programmable through the control with usable rpm range from 1,200 to 18,000 rpm. The design of the motor and frequency inverter provides constant power output between 9,000 to 18,000 rpm.

4 Spindle rotation, RH or LH, is programmable. Vertical Boring with 50 Spindles Weeke Unit #0066 The vertical boring head is located on the right side of the y-axis support beam. There are two independent boring blocks, each with their own Y-axis control. The boring blocks have 25 vertical spindles per block, for a total of 50 spindles on the machine. Of the 25 spindles in each block, fifteen (15) spindles are oriented in the X-axis; eight (8) spindles are oriented in the Y-axis. These spindles are on 32 mm centers. Two re-enforced spindles, for large drills up to 35 mm in diameter, are offset from the in-line boring spindles. The vertical spindles are designed with a mechanical locking feature, which adds rigidity and stability (accuracy) to the drilling process. The spindles are also equipped with a quick-change tooling feature for the drill bits. Standard drill bits equipped with a quick change pull-stud are easily inserted into the spindle and locked in place with this system.

5 The drill spindles utilize standard boring bits, 70 mm long, up to 25 mm in diameter, with 10-mm diameter smooth shanks. The drill bits require a quick change pull-stud be installed at the end of the drill bit. A kW motor drives the vertical-boring gearbox. Spindle rpm is programmable between 1,500 to 7,500 rpm. Technical Specifications MS #29015-29018, February 14, 2006 Page 3X-Axis Horizontal Drilling Weeke Unit #1121 The horizontal drilling block has two drilling spindles. One spindle is oriented to the left and one is oriented to the right. Spindle RPM is programmable between 1,500 to 7,500 rpm. Maximum horizontal boring depth is 45 mm. Grooving Saw Weeke Unit #1016 The X-axis grooving saw is powered by a kW, 60 Hz motor. It is installed at the front of the Machining head. 100-mm diameter saw blades are required for this unit. Spindle rpm is programmable between 2,000 and 7,500 rpm. Maximum Workpiece Thickness Limitations Complete Processing Maximum Workpiece Thickness Limitations Routing Only Technical Specifications MS #29015-29018, February 14, 2006 Page 4 Panel Support Benches Weeke Unit #0300 Six (6) panel support benches have four (4) vacuum pods each.

6 Three of the vacuum pods are 145 mm x 145 mm x 36 mm (height). The fourth vacuum pod is 75 mm x 145 mm x 36 mm (height). The support benches have a control button conveniently located on the front to disengage the pneumatic brakes for the X-axis adjustment of the bench. With six (6) support benches, it is possible to load the machine with two (2) work pieces at a time. Metric scales are located on the machine for easy positioning of both the panel support benches and the vacuum pods along the benches. Panel Feeding Rails Panel feeding rails are attached to one side of each support bench (can be moved to either side). The rails move upward to provide a smooth surface for loading and unloading. The rails retract downward to set the panels on the vacuum pods. Part Positioning Stops There are two sets of positioning stops on the machine. One set is located at the back of the machine and is used for positioning large parts.

7 A second set of stops is located at the front of the support benches and is used for positioning narrow parts. Either set of stops can be used for positioning left-hand or right-hand parts. Vacuum Pump A powerful vacuum pump with 100 M3/hr capacity has enough reserve suction for the most demanding jobs. Dust Extraction Efficiency Dust extraction efficiency is maximized by two dust collection ports, one 200 mm in diameter, the other one 160 mm diameter, with individually controlled connections to the router, vertical boring blocks, and grooving saw. As each Machining unit is activated, dust ports to other devices are automatically closed. Perimeter Fence A perimeter fence helps prevent accidental intrusion from the ends or back of the machine. Technical Specifications MS #29015-29018, February 14, 2006 Page 5 Safety Mats Safety mats will assist in stopping the machine if the operator enters the working area while the Machining head is in operation.

8 The mats are divided into three (3) independent zones so you may load or unload parts at one end of the machine while the machine continues to work on the opposite end.
